US 6,733,813 B2 · Process for producing acids-enriched juice and acids-reduced juice

Abstract

A method is described for processing fruit or vegetables, e.g., cranberries, into two different juices. One of the two juices has a relatively high level of acids. The other of the two juices has a relatively low level of acids. The method of the invention entails providing three juice streams. The first juice stream is passed through a nanofiltration apparatus or some other apparatus that is capable of preferentially removing acidic compounds from the raw fruit or vegetable juice feedstock. This process creates two juice fractions: a juice fraction that is relatively enriched in acids and a juice fraction that is relatively reduced in acids. The second juice stream is combined with the juice fraction that is relatively enriched in acids to create a juice that has a relatively high level of acids. The third juice stream is combined with the juice fraction that is relatively reduced in acids to create a juice that has a relatively low level of acids.

Dependent claims

A method comprising:

(a) providing a flow of fruit juice that is substantially free of insoluble fruit solids;
(b) dividing the flow of fruit juice into at least a first juice stream, a second juice stream and a third juice stream by passing the flow of fruit juice through a ratio divert mechanism;
(c) treating the first juice stream to preferentially remove acidic compounds thereby creating an acids-enriched juice stream and an acids-reduced juice stream;
(d) combining the acids-reduced juice stream with the second juice stream to create an acids-reduced fruit juice;
and
(e) combining the acids-enriched juice stream with the third juice stream create an acids-enriched fruit juice.
